2024 Crustal Deformation Modeling Workshop

2024 Crustal Deformation Modeling Workshop

June 10-14, 2024

Colorado School of Mines, Golden, CO

Agenda

Preparing for the tutorials

We recommend using the PyLith tutorials* and documentation available online to become familiar with PyLith before the workshop. The more familiar you become with the software, the more you learn during the two days of tutorials. There will only be small changes in PyLith between now and the workshop.

*You must be logged into geodynamics.org to access course materials through this link.

Posters and Lightning Talks

We encourage you to bring a poster and present your research. You can also present a lightning talk (3 minutes) on your poster or some "big idea" for advancing our scientific understanding of crustal deformation. Please indicate on the registration form if you plan to bring a poster and/or present a lightning talk. We will organize the poster and lightning talk sessions based on the registration information.

Tutorials

About 60% of the time will be devoted to tutorial lectures with instructors providing background information and running examples. The other 40% of the time will be devoted to "tinker time" during which participants can run the examples at their own pace, develop their own simulations, and get help from the instructors.

Tutorials will cover the use of PyLith for running simulations of crustal deformation, Gmsh for discretizing the domain, and ParaView and PyVista for visualization. All of these tools are free and open-source. There will also be discussion of other modeling tools during the science talks.

Important

PyLith v4.1.2 is now available.
Slides and recorded videos are being posted on the CIG website.
Gmsh Python API

Wednesday June 5 10:00am Pacific Time: Getting Started Help Session

This online help session is intended to answer questions from users and resolve problems encountered during installation or running simple examples. The format will be an interactive Q&A session .

Monday - Tutorials 

These tutorials will provide a discussion of beginning and intermediate meshing and modeling topics. Prior to the workshop users should have installed the software and worked through some of the examples provided in the PyLith manual.
